Want to get a cream foundation of many shades. How should I mix colors? The color currently ordered is Beige - Beige Iron Oxides EasyMix™ White - White Iron Oxides EasyMix™ Yellow - Yellow Iron Oxides EasyMix Red - Red Iron Oxides EasyMix™ Black - Black Iron Oxides EasyMix™ Can you get several shades of lighter and darker colors in a simple way? You should use beige as the main, then lighten and darken by mixing white alone? Or should I use yellow and other colors mixed with it? Thank you.

Hello, Red + Yellow + White = Beige. You can bring Beige to adjust the tone to your skin by adding Red Yellow White and Black.
